550 + 550 = 1100
it can't equal 550....i think it equals 15
The answer = 4560
No. It equals 15.
for 5+5+5=550, you'll have to add one line to the plus so the plus will look like a four. 5+545=550
5 + 5 + 5 = 15
That equals 550.
Putting a top to bottom diagonal strike through the equals sign ( ≠) makes the sum 5 plus 5 is unequal to 550.
690 decimetres equals 69 metres
5 + 5 + 5 ≠ 550
You can achieve this by concatenating the numbers as strings: 5 + "5" + "5" = "555". Then interpret this string as 550 by treating the last digit as the tens place value.
Put a diagonal line through the equals sign to make it "does not equal".
